OK, now I'm confused...

I was under the impression that all I-frames, improved or not, had the round trigger guard rather than the elongated one that was retained on the J-frames. Is there a round trigger guard improved I-frame similar to the Baby Chief, then a later (more) improved I-frame with the elongated trigger guard? This would give a long trigger guard with a short cylinder window, right? My head is starting to hurt again!
